I guess most of us have wondered at one point or another what this message means: "INFO: The Apache Tomcat native library which allows optimal performance in production environments was not found on java.library.path" in the catalina.out log.
Only recently have I spent time trying to figure out the meaning of this message. This message is logged on Tomcat startup if Tomcat cannot find the Native library. Tomcat works fine without this library, but not as optimal. I have spent some time trying to get the Tomcat Native library to work under Fedora. I thought it might be a good thing if I shared my experience in the matter. A tomcat-native.tar.gz archive is packaged in the bin directory of the tomcat binary and I guess it probably is straightforward to install the library from this package, but the deployment model that I am using is such that there is no compiler on the machine where Tomcat is installed. I had to build an RPM in order to install the Tomcat Native library on the machine. As pointed out by Jonas Pasche, the SPEC file that is delivered with version 1.1.7 of Tomcat Native library is broken, and I had to fix it before being able to get the RPM to build. Look at http://jonaspasche.com/patches/tcnative-1.1.7-bugfixes.patch for a description of the required changes. After I installed the APR and the Tomcat Native RPMs, Tomcat was still showing the info message. I found out looking at the list that I needed to point Tomcat to where these libraries where stored. The trick is to set LD_LIBRARY_PATH to point to them, for instance, adding this line to catalina.sh: LD_LIBRARY_PATH=/usr/lib:/lib and ensuring LD_LIBRARY_PATH environement varaible is visible Tomcat. That still didn't fix the problem completely. I figured after running some tests that Tomcat was looking for a libtcnative-1.so file, but the RPM installed libtcnative-1.so.0. After I created a libtcnative-1.so softlink that pointed back to libtcnative-1.so.0, Tomcat loaded the native library. There are some changes to do in the server.xml file (for instance the SSLCertificateFile parameter needs to be configured). See http://tomcat.apache.org/tomcat-6.0-doc/apr.html for details on the parameters.
